When attempting to optimize radiation use during a fluoroscopic procedure, the aim is to acquire images that adequately address the needs of the different tasks which together comprise the procedure. Naturally, each procedure and its different segments may yield a variety of needs and related images. Ideally, these images should possess just enough information to adequately address the uncertainties of the task at hand. While complex tasks might justify acquiring high quality images with their minimal uncertainty, low quality images with their higher uncertainty, are often sufficient for simple tasks. This shift in perspective indicates a need to focus on the factors that govern the clinical utility of images rather than the more traditional concept of image quality.
在荧光透视检查过程中试图优化辐射使用时，目标是获取能够充分满足构成该检查过程的不同任务需求的图像。自然地，每个检查过程及其不同部分可能会产生各种需求和相关图像。理想情况下，这些图像应具备足够的信息，以充分解决手头任务的不确定性。虽然复杂任务可能需要获取具有最小不确定性的高质量图像，但具有较高不确定性的低质量图像通常足以满足简单任务。这种观点的转变表明需要关注决定图像临床效用的因素，而不是更传统的图像质量概念。
